ROAD-OILER.

Specification of Letters Patent.

Application filed May 13,

1910. Serial No. 561,062.

To all whom it may concern."

Be it known that I, WILLIAM H. GAILOR,

a citizen of the United States, residing at Saratoga Springs, in thecounty of Saratogaand State of New York, have invented an Improvement inRoad-Oilers, of which the following is a specification.

My invention relates to improvements employed in connection with theroad oiling devices shown and described in my application for LettersPatent of the United States filed July 24, 1909, Serial No. 509,458. Inthis and other devices employed by me as road oilers, a steam boiler andfire thereunder have been employed and the steam generated was utilizedto heat the oil or other material employed to effectits delivery on thesurface of the road. In this device much valuable heat and energy werelost and the apparatus could not be run with a maximum economy or theoil delivered upon the road carrying sufficient units of heat.

In my present invention the steam boiler with its fire and the use ofsteam therefrom for heating the oil or other material are dispensed withand a fire is employed under the tank holding oil or other suitable material, and this fire heats the oil or other suitable material employed,and the hot gases or products of combustion of said fire are utilizedand directed through a heating chamber containing a reservoir, adistributer reservoir'and connecting pipes for the oil or other materialto bedelivered uponthe road so that these smaller bodies containing thematerial moving therein are additionally heated by the hot products ofcombustion coming from the combustion chamber and passing away by one ormore stacks or chimneys rising from the heating chamber.

In the'drawing, Figure 1 is an elevation and partial sectionrepresenting the essential features of my improvement; the section beingtaken through the case of the heating chamber and also through the caseof the distributer reservoir. Fig. 2 is an elevation and verticallongitudinal section at about the dotted linew, w, of Fig. 1, and Fig. 3is an elevation and vertical longitudinal section similar to the sectionFig. 2 but illustrating another form of my apparatus.

Similar letters of reference in the several figures indicate similarparts.

In these figures of the drawing, the oil tank or tank holding othersuitable material to be heated and delivered upon thgsurfa'ce of a roadis represented at 10, and at 11 there is a long pipe reservoir andbetween the tank and the reservoir a pipe 12 and a controlling yalve 13.therein. The distributer reservoir 1s represented at 14 and connectingthe same and the reservoir 11 there are series of pipes 15 with valves16 therein.

The distributer reservoir 14 is preferably formed of plate metal withone side fixed and one side adjustable so that there is a delivery slot17 between said two parts which is regulated by one or more adjustingbolts 18. So far as just described, these parts agree substantially withsimilar parts shown and described in my aforesaid application and whichare employed for bringmg .the oil or other suitable material from acommon tank 10 to the reservoir 11 and therefrom to the distributerreservoir 14 and delivering the same upon the surface of the the same.

The special features of my present invention comprisea casing beneathand along the tank 10 forming a fire-box or combustion chamber a, whichmay be constructed in any desired or suitable manner and at one plate (1The caslng comprisingsides 2, 4, a bottom 3, a top 5 and ends 6 of platemetal is employed and surrounds and entirely incloses the reservoir 11,pipe 12, valve 13, distributer reservoir 14, series of pipes 15 andtheir valves 16, with the handles of "the valves 13 and 16, extendingthrough the top operation. The casing of these parts comprises a heatingchamber b connecting with the combustion chamber a and rising from Ihave in the drawing shown two stacks, one at each side of the stem andhandle of the valve 13 which permit of the operation of the valve whenin the position illustrated. I have shown Within this heating chamber aswinging bathe-plate d upon a'shaft 0Z both of which preferably run theentire length of the heating chamber 5; there being a handle (P atoneend upon the shaft 03 outside the heating chamber for actuating theswinging battle-plate. This baffle-plate comprises parts at an. angle toone another with the shaft 03 located at the intersection.

In Fig. 2 I have shown the baffle-plate d in .its two extreme positions.In the full line position one edge comes up against the end ispreferably provided with a bafllethis heating chamber is one or morestacks c.

Patented Sept. 10, 1912 road, oiling'the road or otherwise treating 5and side 4 of the casin for their proper under side of the tank 10 andthe other edge rests upon the reservoir 11. In the dotted position theone edge rests upon the upper surface of the baffle-plate a and theother edge comes up against the under surface of the pipe 12. r

The casing constituting the fire-box a. may be of any desiredconstruction for holding a fire of Wood or coals for heating the tank 10and the contents thereof; the portion shown in Fig. 2 being only thecombustion chamber away from the fire portion.

All the hot gases and products of com-- bustion must pass beneath thetank 10 and 5 the upper edge of thebatiie-platea ,throi1gli the heatingchamber 6 and away by the stack. In the full line position of theswinging battle-plate d these products of combustion are by saidbaflie-plate diverted down into the lower port-ion of the heatingchamber 1) where they entirely surround the reservoir 11, distributerreservoir 14, pipes 15 and valves 16 and must pass beneath thebattle-plate d before rising into the upper part of the heatingchamber]; around the pipe. 12 and valve 13 before escaping by the stackor stacks 0. Thus the devices through which the oil or other materialspass from the tank to be distributed upon the road are not onlythoroughly heated,

but brought to a high heat and the contents brought to a higher heatthan would be possible by the use of steam as I have heretofore employedit. The full line position of this swmging baffle-plate is that employedin the operation of the device, while the dotted line position is thatusually employed in starting the fire where one edge of theswinging'bafiie-platerests upon top 40 of the bafiie-plate a and theother edge comes beneath the pipe 12, giving ready access to the stackso'r chimneys. In fact I prefer to put the handle d upon the shaft 01 ofthe swinging baffle-plate in such a position that it will assist inkeeping the baflieplate in the full line position Fig.2, for use.

In the device of my invention, the hot oil or other material is evenlydistributed upon the ground or surface of the road closely adjacentthereto. The bottomof the casing or heating chamber also comes close tothe ground and serves to heat the surface of the earth somewhat beforethe oil or other hot material is delivered thereon, and in i this mannerboth the heating of the material to be delivered and the heating of thesurface to receive the material being delivered are facilitated.

0 Referring particularly to Fig. 3, which represents a second form of myapparatus, similar parts having similar letters and numerals ofreference as in the other figures, except that in this figure the casingbelow and at the rear of the oil tank 10 is so arranged and constructedas to provide an uptake chamber e, with an opening at uptake still atthe rear of the uptake 6 designated by the reference letter 1 in whichbelow the plane of the valve or damper 7 is placed a valve or damper 8,while a baffleplate of fixed construction is indicated at d, and in theoperation of this structure the heated gases and products of combustionfrom the fire-box or combustion chamber a beneath the oil tank 10 assover the baffle plate a beneath the xed baffle-plate d circulatingthrough the heating chamber and around the various devices thereinconveying oil or other suitable material from the tank 10 up thepassage-way f, with the valve or damper 8 in the upright open positionshown in Fig. 3 and away by the stack 0. Thus the products of combustionand hot gases are utilized to thoroughly heat the various conveyingdevices in the heating chamber 6.

In starting up the fire under the tank 10 it is preferable to close oflthe valve or damper 8, that is, by turning the same into a horizontalposition and by opening the valve or damper 7; that is, by turning thesame into a horizontal posit-ion, in which case the passage-way beingclosed off the products of combustion pass up the passageway e throughthe throat, past the damper or valve 7 and away by the stack 0.

When the fire gets going and it is desired to heat up the devices in theheating chamber b, the damper or valve 7 is turned into a verticalposition as shown in Fig. 3, to close off the connecting throat betweenthe passage-way e and the stack; thus compelling. all the products ofcombustion and hot gases to pass through the heating chamber 6 aroundthe devices contained therein and up the passage-way f to the stackc.
